The embodiment of the invention shown in the drawings comprises a machine supported by truck wheels designated by the numeral 20. which are secured to axles 21, journaled in hearings 22 formed in a main traine plate 23. The plate 23, as shown in Figs. 3, 4 and 5, extends for a considerable distance in the front and rear of the truck wheels 20, and as shown in Fig. 9, is rein forced by longitudinally extending ribs 24. Mounted on the plate 23, as shown best in Fig. 11, is a motor 25 which drives a worm 26 through reduction gearing carried in a gear casing 27. The worm 26 meshes with a worm wheel 28 and is provided with a number of worm threads so that the pitch of the threads is suiticiently steep to permit of backward driving of the worm wheel and worm. The worm wheel 28 is mounted on a shaft 29, which is journaled in a side bracket 30 .secured to the frame plate 23. The shaft 29 is connected with the axles 2l of the truck wheels 2O by means of beveled gears 31. Brake shoes 32 are sup orted by links 33 in position to bear upon die wheels 20 and are moved into and out of contact with the truck wheels by means of links 34 and a lever 35 which is held in adjusted positions by a tooth segment 36. The lever 35 is connected with a shaft 37 which extends across the frame 23 to operate the brakes on opposite sides of the truck'.

The frame plate 23 is provided near its center with a main pivot pin 40, by means of which a forward supplemental frame 4l and a rear discharge conveyer frame 42 are connected with the truck. The frames 4l and 42 are provided with an upper pivotal. connection 43 which is secured to the conveyer frame 42 by a yoke 44 and to the supplemental frame 41 by a yoke 45 and adjustable screw rods 46. By this arrangement the supplemental frame 4l and the conveyer frame 42 may be independently swung laterally upon the main frame plate 23, and also relative to one another. The discharge conveyor frame 42 is provided with a hopper 47 which converges toward the rear, as shown in Figs. 6 and 7. to form the sides of the convcyer frame. The rear portion of the conveyor trarne is provided with movable sidc boards 48 hinged to the main portion 0f the frame at 49 and having :i locking mecha- A.nism 5() for holding t-bcm in upright posi tion. Similar side boards 51 are provided for the converging walls of the hopper portion 47. The side boards 48 and 51 may be folded inwardly to permit the machine to travel through low places in the mine cham` ber. The rear end of the frame plate 23 provided with a curved I-beam 52 which forms a sliding support for the convvyer frame 42. The upper bar ot' the I-heam 52 lits in a slot 53 formed in a horizontally vxtending plate 55 secured to thc convvyvr frame 4:2v by upright plates 56. An vndlvss conveyor 57 is arranged to travel over a hvd plate 58, as shown in Fig. ll. thv hed plate being supported at its outer vdgvs b v tht` side walls of the frame l2 and heing bent over, as shown at 59. to cover the chains otl the von- Veyer. Angle bars (it) may hv provided t'or guiding thv vonvvyvr upon the bed plate 58. The convvyvr is driven hy a motor 61 mount'- ed on the plate :35. and driving a shaft 62 which carries sprocket wheels (i3. over which the conveyer 57 passes. Secured to pins 64, adjacent the rvar end of the frame plate 23, as shown in Figs. 2i and 14, there is provided a pair of segmental shoes 65 which have a detachable pivotal connection with the main plate 23. The shoes 65 on one side of their pivot pins 64 are shaped to hear upon the track rails 66 having their outer periphery arranged to form an arc which will rest upon the rails, although the shoes may be tilted to diterent angles about their pivot pins. The sides of the shoes, opposite the pins 64, are provided with ears 67 to which screw rods 68 are fastened by means of pins 69. The rods 68 at their outer ends carry pointed contact members 69 which may be forced outwardly along the rods 68 by threaded hand wheels 70. The contact members 69' may be forced into engagement with the roof of a. mine chamber to hold the frame of the machine rigidly in position upon the track 66, and when this is done, the shoes 65 bear upon the track to take the downward thrust of the rods 68, and thus prevent tilting of the frame of the machine. It is apparent that the rods 68 may be swung laterally to engage the sides of the mine chamber, or may be inclined downwardly, or adjusted to a variety of positions in order to secure proper anchoring of the machine frame. The conveyer 57 may discharge its material into a car 71 shown in broken lines in Fig. 3, or it may be swung to one side of the track to discharge material into the gob in ease material is encountered which is not of sufficient value to justify its remo "al `from the mine. A controller 72 is located adjacent the rear end of the eonveyer frame 42 and is connected with the motor 61. by which the conveyer 57 is driven so that the movement of the conn veyer may be controlled from the car 7l.

The supplement d frame 4l is provided with a rearwardly extending arm 73 which connects the frame with the pivot pin 4t) and which is bowed upwardly. as shown in Fig. 9, to clear the bearing .22 l'or the front truck axle. The frame is provided with a rear wall 74 and side walls 75 which extend forwardly a considerable distance beyond the front end of the base plate 7 3. The bottom plate 76 of the frame 41 extends forwardly a greater distance than the main portion ot the side walls and to a position nvar the l'ront end of the machine. The walls 75. adjacent their hasv, are otl'set outwardly, as shown at 77 in Figs. L .3 and 1;), to t'orm a slidvway for rack bars 78, thv purpose ot which will be explained latvr. As ,shown in Figs. 5 and 8. the main portions otl the side walls 75 are discontinued some distance in thv rvar ot' theI front end ot' the machine. hnt the slideway 77 and their racks 78 extend a considvrahle distance in front of the forward end of the main portions ol' the side walls. The snpplemental frame 4l supports an inclined extensible conveyvr 79 which is provided with main side walls 8l) which are tixed in position, and which rest, as shown in Figs. 9 and 10, at their rear ends upon the upper edge ot the rear wall 74 of the frame 41, and at their forward end upon thc front end of the floor plate 76. The side walls 8() are connected by a eonveyer bed plate 81 which is located a slight distance above the lower edges of the side walls, and a short bed plate 82 connects the lower edges of the side walls 81 near their front ends. A pair of conveyer chains 83, connected by flights 84, constitute a conveyor, one run ot which travels upwardly over the bed plate 8l, while the return run is supported at the forward end of the convcyer by the short plate 82. The unsupported portion ot' the conveyor, in the rear of the plate 82, engages sprocket wheels 85, carried by a shaft 86, and driven hy a motor 87, which is mounted upon the rear Wall 74 of the frame 41. The upper portions of the walls 80, as shown in Figs. 9 and l2, are provided with hinged extensions 88 having a latch 89, Fig. 4, for holding them in upright position and arranged to be folded inwardly to permit the machine tomove heneath a low roof.

' As shown in Fig. 12, the bed plate 81 is bent to form inwardly projectinglr flanges 9o, upon which sliding slices 91 are supported, and along which they are free to move in the longitudinal direction of the conveyor. The shoes 91 are connected by a shaft 92, which supports a sleeve 93 formed at the upper end of a supplemental conveyor hed plate 94. The bed plate 94 is connected at its lateral edges with side walls 95, which cooperate with the bed plate 94 to form a supplemental conveyer frame, supported at itsl rear end by the shoes 91, and slidahle longitudinally along the supporting flanges 90. The forward end of the supplemental convever frame is connected by means of a shaft 96, as shown in Figs. 8 and 10, with inwardly projecting lugs 97 formed on the v P' n inner faces of thtI rackl bars t8. The foiward end of the bed plate 94 is formed into a sleeve 98 over which the return ran of the conveyor chains 83 are guided after they loo lli)

h a re -fed over the hed plate 82. In this n ai eonreyer is directed onto the upper .urfitee oit the lied plate 94. After the eenn Ytfyer paeaes aronnd pulleys 99 and the sieei'e 93 at the upper end of the bed plate 94. it returns in an idie run to the lower end of the Stationary eonveyer traine where it is ptiide'l around pulleys 10ft on a tixefl Shaft tilt. .By this arrangement hoth of the active rune of the Conveyor whieli travel upon the upper surfaces of the lied plate1 tt and 91, 'ir-ore upwardiy when the aproeiiet wheel: 85 t, rotated in a eloekwiae dirertion` as viewed in. Fig. 9. This will canse material on the bed plate 94 to he carried to the upper end of this: plate and diarhargii-d onto the lied plate Si., along whieh it continues to mow upwardly until it is diseharged `into the hopper 47. Iinee the ldtatt Slt; at the forward end of the snlipleniental bed plate 91 if: eonnet'ted with the raeli bars 78. torward inorementy of these bars in their slide ways: 77 will carry the front end of the supplemental eonveyer forwardly and rauw the rear end .aupportetl by the, Shoes 91 to Slide forwardly and downwardly along their Sup porting flangea. Such forward inoven'tent ot the .-.uijpleinental t'onveyer wiil noty alter the length of eliain required.

During this shifting movement the floor plate 76 slides upon the upper surface of the main frame plate 23. The motors for driving the various parts ot the marhine, with the exception of the rear eonveyer, are eonneeted with a series of eontrollers 120 mounted on one 0f the side plates 75 of the supplemental frame. runner-board 121 is hinged to the base plate 23 adjacent the wntrollers for the mo tors.

As shown in Figs.. F. 8, 1() and 13, a shaft 122 journaled in the rat-lt liars 78 near their forward endal and extends transversely of the niaehine from one of the rael; bars to the other. The bearingsv for the shaft 122 are extended by means; of bosses 123 on the inner fares of the liars, and adjacent these horse is a pair of sleeves 121 keyed to the shaft. As shown best in Fig. 10, the sleeves 124 are provided with arms 125 whieh extend forwardly from the shaft 112 and support a stroop 126 rigidly upon the shaft for vertical movement about the axis ot' the shaft whenever the shaft is rotated. As shown in Fig. 8, the rear portion of the :'eoop eorreaponds in width to the width of the front end ot the eonveyer connected with the shat't 9G supported by the raek bars. The front, end of the scoop is flared laterally so that its forward edge is longer than the width of the eonveyer, and this edge is provided with a series of teeth 127 for engaging the material to be loaded. The Scoop 126 is swung upon its pivotal support by n1ean of a worin wheel segment 128 keyed to the l@haft 122 and meshing with a worin 12S). journaled in a hearing 130, whieh iS toi-ined integral with a gear Casing 131. "the gear asing 131 is supported upon the traine of a motor 132. by means of which motor the gearing within the easing is driven. The motor 12 is carried upon a platform 133. whith in turn is lanppoited by a #tanda rd or braeltet 125i i'nojerting upwardly from the raek barsA 7S and seeuretl rigidly thereto. The braeket 134 is so positioned relatire to the raek bars` that when the liars ,dide along their guidewayal 77. the braeket will more along the inner fare of the ,guidewat; 7.7 adjacent that portion of the guidewai.'4 whieh extends in t'ront ot the main portion of the ide wall5l 75. The worin wheel and worin and 129 are preferably of the witlotylting type. so that the shovel 1213 will lle held in whatever angular position it is ainsi-il to naw-unie. ll'orni gearing tot' tilting the shovel llfl will enable the latter to lie moved up very powerfully which is pai-lieulai-ly de iralrle when Coal is to be loosened preparatory to loading: furthermore. the worin aring enable he scoop to be lowt-red poxitively and therefore prevents it from being dropped by gravity.

1n order to Connterbalant'e the weight of the scoop 126, the shaft 122, at the end opposite the worm segment 128, is provided with a crank arm 135, which is rigidly secured to the shaft, and is connected at its outer end to a rod 136, secured to a counterbalancing spring within a tubular casing 137, as shown best in Figs. 5 and 8. The rear end of the spring casing 1217 is pivotally connected to a standard 138 projecting upwardly from one of the racks 78 and arranged to move with the rack along the inner face of its guideway 77 in a manner similar to the support for the motor 132. It will be noted that the spring counterbalance always acts in an upward direction upon the scoop 126 and that the bar 1:16 is above the pivotal axis otl the scoop, even when the scoop is in its lowcrmost position, as shown in Fig. 5. i

The racks 78 at their forward ends are provided with screw jacks 135), which may be adjusted by hand wheels 140 to regulate the distance. of their foot plates 141 above the surface of the mine tloor. Since the scoop 126 is located at a considerable distance in front of the supporting truck. it will he apparent that when the scoop is tilted about its axis to lil't material. there will be a tendency for the front end of the machine on which the scoop is supported to tilt downwardly. This will he especially true when the racks 78 are extended to a position in advance of the front end of the supporting frame. Any downward lnm'ement of the scoop, due either to a tilting of the entire machine caused by the load upon the scoop, or to a springing ol the supporting frame produced by the same cause, is arrested by the jacks 1119 which come into contact with the floor of the mine chamber before the downward movement of the scoop is sufficient to interfere with the operation of the machine. 'l`he jacks will continue to support ther scoop so long as tho weight is sutlicient` to cause them to engage the mine floor, and if it is desirable to move the scoop laterally or longitudinally at such times, the jacks may be caused to slide upon the surface of the tloor a suflicient amount to permit .sinh movement. As soon as the weight upon tht` scoop is removed, the frame will return to its original position and thus raise the jacks away from the floor.

ln operation, the shoveling machine is transported along the` track in the mine chamber until its forward end is brought adjacenty the material to be loaded which has been previously loosened by any of the wellltnown methods employed for this purpose. The truck and main frame of the machine is then anchored in this position by means of the braking mechanism and the anchoring jacks 68 previously described. The shovel 126 is then tilted about its axis 122 into proper position to engage the material,

and the conveyer 83 is sety into operation by means of the motor S7. The rack bars 78 are then driven forwardly to force the nose of the scoop 126 into the material to be loaded, and when the scoop has been filled it is tilted about its axis 122 by means of the worm wheel segment 128 and caused to dump from its rear end onto the conveyer 9,3. 1t should he noted that the supplemental sliding frame for the conveyer S3 maintains the front portion of the conveyer in position to receive material from the scoop 126 independently ol' the position ot' the scoop relative to the frame of the machine. ln other words, the scoop may be dumped when it is extended to its extreme forward position by the Yrack bars 78, or when it is in its rearmost position, or at any position intermediate the two. The extensible conveyer 83 will carry the material backwardly and discharge it into the hopper 47 no mattei' in what position the scoop happens to be at the time itl is dumped. ll`he scoop may, therefore, be pushed forwardly a .sutlcient amount to lill thc scoop, and the material thus gathered may be dumped and the scoop lowered for a second lilling without being retracted. The scoop may also be swung laterally about the pivot 4t) to gather material at the sides of the mine track in a wide chamber. and the parts will operate in the sameI manner as they do when the scoop is directly in front of the machine.

In the modified construction shown in Figs. 15 to 19, inclusive, the scoop 142 is not usually swung upwardly to dump its contents onto the conveyer, but instead the conveyor chains 83 are extended forwardly around a shaft 143 located in the nose 144 of the scoop. 'l`he scoop is pivotally supported by bearing lugs 145 and 146 calried by the rack bars 78. and a worm gear segment- 147 is connected with the pivot pin extending through the lug 146. This segment is rigidly connected with the scoop by means of the pivot pin and engages a worm 148, by means of which the Scoop may be swung upwardly to dumping position or to hold it in position to clear the track when the machine is being transporttal from one position to another. 'lhe worm gearing 147, 148 may be made of the non-sel'f-locking type when it is desired that they scoop 142 shall haver freedom ot' movement up and down abouty itsI pivotal support while nioring over an irregular floor and the beveled nose 144 alone relied on to keep the material in Contact with the floor and preventing it from riding up on the material. Then the, floor is substantially horizontal` however` the worm gearing 147`v 148 may be made of they self-locking type so as to hold the scoop down in adjusted position and assist; the beveled nose 144 in keeping the scoop i'n Contact with the floor during the loading operations.

The .self-locking type of worm gear'in will also enable the scoop to be held at adjusted elevation when it is retracted with the load while tbc ronveyer is transferring the material toward loading position. vlVliether the worm gearing 147, 148 is of the non-selflocking type or of the self-locking type it will enable the scoop to be positively lowered and prevent it from being dropped by gravity. The worm is driven by a motor 149 carried upon the rack bars 78 in a manner similar to that described in connection with the forni of the invention previously discussed. At the side of the scoop, opposite tbe worin segment 147, a crank arm 150 is secured to the pivot pin passing through the bearing lug 145, :ind the arm 150 has its outer end connected to the end of a Counterbalance rod 151, similar to the counterbalance previously described. It will be seen from Fig. 1T that this form of the invention diilers t'roni the other torni in that the crank 15o is below its dead center when the scoop 142 is in its lowerinost position. By this means the rountei'balance tends to hold the scoop in its operating position after it has been swung downwardly to rest upon the floor ot' the mine ibamber. It it is found desu-abb, a supplementary locking pin 152 mayv be provided to lock the scoop in this pos-tion, but ordinarily the locking action ot' the eoumei-balancing spring will be Sullieienty l'or this purpose. The scoop 142 is provided with side walls 153 which overlap tbe walls H5 of tbe sliding conveyor frameso :is to eontine the material carried rearwardly b v the conveyor.

In operating this forni of the invention the naa-bine trame is anchored in position in the mme chamber in themanner previouslr de-eribed and the scoop is carried forwardly b v the rack bars 78 to force the noscpieee beneath tbe loosened material to be loaded. As the scoop enters the material, the material is deposited directly on the conveyer and carried rearwardly toward the car into which it is to be. loaded, and there is no necessity for raising tbe scoop as in the form previously described but such lifting of the .seoop may be eti'eeted whenever desir'ed. The machine may be operated to gather material at either side of the track in the same wav :isl the other t'orni of the invention.
